用途：近年来，智能手机、平板电脑和电子书阅读器等消费电子设备的应用越来越广泛。这些设备中的许多都包含可访问性功能，例如大字体和语音。轶事经验表明，视力受损的人经常使用这些系统。在这里，我们调查了自认为有视力障碍的人，以确定他们对这种设备的使用情况。方法：通过口头宣传、社交媒体和网络等方式对视力障碍人群进行网络调查。受访者被问及人口统计信息，他们拥有什么设备，他们使用这些设备的目的，以及他们使用了什么辅助功能。结果：共收到完整回复132份。26%的人报告说他们没有视力，其余的人报告说他们有低视力。117人（81%）使用智能手机。那些没有视力的人使用智能手机或平板电脑的可能性与那些视力低下的人一样。59%的智能手机用户认为语音很有用。51%的智能手机用户使用摄像头和屏幕作为放大镜。48%的受访者使用平板电脑，17%使用电子书阅读器。不使用这些设备最常见的原因包括成本和缺乏兴趣。结论：智能手机、平板电脑和电子书阅读器可用于视力障碍人群。视力低下的人和没有视力的人都能使用语言。我们（自选的）小组中的许多人将他们的智能手机相机和屏幕用作放大镜，其他人则将相机闪光灯用作聚光灯。
Purpose: Consumer electronic devices such as smartphones, tablet computers, and e-book readers have become far more widely used in recent years. Many of these devices contain accessibility features such as large print and speech. Anecdotal experience suggests people with vision impairment frequently make use of these systems. Here we survey people with self-identified vision impairment to determine their use of this equipment.Method: An internet-based survey was advertised to people with vision impairment by word of mouth, social media, and online. Respondents were asked demographic information, what devices they owned, what they used these devices for, and what accessibility features they used.Results: One hundred and thirty-two complete responses were received. Twenty-six percent of the sample reported that they had no vision and the remainder reported they had low vision. One hundred and seven people (81%) reported using a smartphone. Those with no vision were as likely to use a smartphone or tablet as those with low vision. Speech was found useful by 59% of smartphone users. Fifty-one percent of smartphone owners used the camera and screen as a magnifier. Forty-eight percent of the sample used a tablet computer, and 17% used an e-book reader. The most frequently cited reason for not using these devices included cost and lack of interest.Conclusions: Smartphones, tablet computers, and e-book readers can be used by people with vision impairment. Speech is used by people with low vision as well as those with no vision. Many of our (self-selected) group used their smartphone camera and screen as a magnifier, and others used the camera flash as a spotlight.
